Model 150-180um (GP0165) - General Purpose Glass Microspheres Brochure

In the first stage of refinement, broad distribution glass microspheres are very accurately sieved using a variety of sieving processes to produce extremely sharp cuts.  As the complete particle size distribution of this product is not traceable other than to the start and finish points of the distribution, these beads are particularly useful as general purpose research microspheres or spacer beads in a range of lower grade applications. They may also be used as a preliminary material with which to assess the performance of particle size equipment, after which a higher specification traceable standard may be used as the final calibrant.
